Why is expressed sequence tag library a fitting name for a collection of clones made from mRNA?
please help :((((

Answers

Answer 1
An expressed sequence tag (EST) library is a collection of short cDNA (complementary DNA) sequences that are generated from the mRNA (messenger RNA) of an organism. The name "expressed sequence tag" is fitting because these short sequences are "tags" that identify the expressed genes in a particular cell or tissue.

The term "expressed" refers to the fact that the mRNA is transcribed from a gene and has therefore been "expressed" or made into RNA. The term "sequence" refers to the fact that the cDNA sequences are determined by sequencing the mRNA. Finally, the term "tag" refers to the fact that the ESTs are short sequences that can be used to identify expressed genes in a particular cell or tissue.

Therefore, the name "expressed sequence tag library" is fitting for a collection of clones made from mRNA because it accurately describes the nature and function of the library.

Maintaining a balance between the populations of kelp, otters, and urchins is important for the health and sustainability of the kelp forest ecosystem.

What is the carrying capacity of the kelp forest ecosystem?

In a kelp forest ecosystem, kelp, otters, and urchins have a complex relationship. Kelp is the primary producer in the ecosystem and provides habitat and food for many organisms.

Otters are the primary predator of sea urchins, which are herbivores that feed on kelp. When otters are present in the ecosystem, they control the urchin population, allowing kelp to thrive. However, when otter populations decline, the urchin population can increase and overgraze the kelp, leading to a decrease in kelp abundance.

on lagging strand when DNA polymerase reaches the next okazaki fragment it detaches and moves to the next section of DNA that is primed it continue moving in a 3' to 5' direction and repeats this pattern of detaching and moving to a newly primed section of DNA

Answers

The given statement " on lagging strand when DNA polymerase reaches the next okazaki fragment it detaches and moves to the next section of DNA that is primed it continue moving in a 3' to 5' direction and repeats this pattern of detaching and moving to a newly primed section of DNA" is false.

DNA polymerase does not move in a 3' to 5' direction during replication, rather it moves in a 5' to 3' direction. On the lagging strand, DNA polymerase synthesizes short discontinuous fragments called Okazaki fragments in a 5' to 3' direction away from the replication fork. When DNA polymerase reaches the end of one Okazaki fragment and encounters the beginning of the next, it does not detach from the DNA strand, rather it remains bound to the template strand and continues extending the new fragment in a 5' to 3' direction towards the replication fork.

On the leading strand, DNA polymerase moves continuously in a 5' to 3' direction towards the replication fork, without detaching from the template strand. The process of DNA replication involves complex enzymatic reactions, and it is important to understand the correct directionality and mechanisms involved to accurately explain the process.

What are the four modern-day phyla of gymnosperms?

Answers

Answer:

Gymnosperms consist of four main phyla: the Coniferophyta, Cycadophyta, Gingkophyta and Gnetophyta.

Conifers are the dominant plant of the gymnosperms, having needle-like leaves and living in areas where the weather is cold and dry.

Cycads live in warm climates, have large, compound leaves, and are unusual in that they are pollinated by beetles rather than wind.

Gingko biloba is the only remaining species of the Gingkophyta and is usually resistant to pollution.

Gnetophytes are the gymnosperms believed to be most closely related to the angiosperms because of the presence of vessel elements within their stems.

The four modern-day phyla of gymnosperms are:

Coniferophyta (conifers): This is the largest and most diverse phylum of gymnosperms, with over 600 species. Conifers are typically evergreen trees or shrubs with needle-like or scale-like leaves and cones that contain the seeds.
Cycadophyta (cycads): This phylum includes about 300 species of palm-like trees and shrubs with large, compound leaves and cones that are often brightly colored.
Ginkgophyta (ginkgos): This is a small phylum with only one living species, Ginkgo biloba. Ginkgos are deciduous trees with fan-shaped leaves and fleshy seeds.
Gnetophyta (gnetae): This is a diverse group of around 70 species of shrubs, trees, and vines. Gnetophytes have a range of leaf types and growth forms and can be found in both tropical and temperate regions. Some examples include Ephedra and Welwitschia.
All gymnosperms share the characteristic of producing seeds that are not enclosed in a fruit. They are an important group of plants because they can survive in harsh conditions and are often used for lumber, paper, and as ornamental plants.

since the new strand made of short segments of RNA nucleotides, has a free 3'end what can attach and add nucleotides

Answers

DNA polymerase can attach and add nucleotides to the free 3' end of a new RNA strand made of short segments of RNA nucleotides during DNA replication.

RNA primase first adds a short RNA primer to the 3' end of the template strand, which serves as a starting point for DNA polymerase to attach and add nucleotides in a 5' to 3' direction. DNA polymerase can only add nucleotides to the free 3' end of the RNA primer or an existing DNA strand. Once the RNA primer is replaced with DNA nucleotides, the lagging strand can be joined to the leading strand through DNA ligase.

This process of DNA replication is semi-conservative, meaning that each new double-stranded DNA molecule is composed of one parent strand and one new daughter strand. This mechanism of DNA replication ensures the accurate transfer of genetic information from parent to daughter cells during cell division.

the function of the caecum is to _/_ _ wastes

Answers

The function of the caecum is to absorb salts and electrolytes and lubricate the solid waste that passes into the large intestine.

The cecum's primary roles are to mix its contents with mucus, a lubricant, and to absorb fluids and salts that are left behind after intestine digestion and absorption are complete. A thick mucous membrane makes up the inside wall of the cecum, through which salts and water are absorbed.

In herbivores, the cecum is a food storage area where bacteria may degrade cellulose. The human cecum no longer serves this purpose (see appendix), therefore in people it only serves as a dead-end pouch that is a portion of the big intestine.

The last part of the body to process food is the large intestine, which receives the undigestible components from the small intestine, absorbs water from it, and excretes the waste material known as feces. The rectum and the anus are the organs that the body uses to release feces.

Therefore, the function of the caecum is to lubricate the wastes.

During photosynthesis, pigment molecules in chloroplasts must absorb eight photons (four by each photosystem) for every O2 molecule they produce, according to the equation 2H2O+NADP++8photons⟶2NADPH+2H++O2 The standard free‑energy change ( Δ′° ) for the light‑independent production of O2 is 400 kJ/mol. Assuming that these photons have a wavelength of 700 nm (red) and that the light absorption and use of light energy are 100% efficient, calculate the standard free‑energy change for the process.

Answers

The standard free-energy change for the photosynthesis reaction is -184 kJ/mol.

Since the reaction involves the production of O₂ and NADPH, we can write the equilibrium constant (K) as:

K = [NADPH]² × [O₂] ÷ [H2O]² × [NADP⁺]

Given that Δ′° = -400 kJ/mol, we can calculate the value of K using the relation:

ΔG° = -RT ln(K)

ΔG° = -400 kJ/mol

Assuming the temperature to be 25°C (298 K), and the gas constant R to be 8.314 J/mol K, we get:

ln(K) = ΔG° ÷ (-RT)

ln(K) = 400,000 J/mol ÷ (-8.314 J/mol K × 298 K)

ln(K) = -51.2

[tex]K = e^{-51.2}[/tex]

K = 3.3 x 10⁻²³

Now, we need to calculate the energy (E) of each photon using the relation:

E = hc ÷ λ

where h is Planck's constant, c is the speed of light, and λ is the wavelength of the photons.

E = (6.626 x 10⁻³⁴ J s x 2.998 x 10⁸ m/s) ÷ (700 x 10⁻⁹ m)

E = 2.84 x 10⁻¹⁹ J

Since 8 photons are required to produce one O₂ molecule, the energy required to produce one O₂ molecule is:

8 x 2.84 x 10⁻¹⁹ J = 2.27 x 10⁻¹⁸ J

To calculate the free-energy change (ΔG) for the process of photosynthesis using the relation:

ΔG = -nFE, where n is the number of electrons transferred, F is Faraday's constant, and E is the potential difference.

In this case, two electrons are transferred to produce one O₂ molecule and two NADPH molecules, and the potential difference (E) is 0.95 V

ΔG = -2 x (96,485 C/mol) x (0.95 J/C)

ΔG = -184,000 J/mol

ΔG = -184 kJ/mol
